GRAIN-ELEVATOR.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed Ia-rch 2'1, 1906. Serial No. 308,299.

To all whom it may concern:

Be it known that I, FRED W. CooLEY, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in a Combination Pan, Boot, and Pit for Grain-Elevators and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use. the same.

My present invention relates particularly to grain-elevators employing cup-equipped belts, and has for its object to improve the same in the several particulars hereinafter noted.

The invention consists of the novel devices and combinations of devices hereinafter de scribed, and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a 5 plan view of the improved device, some parts being shown in horizontal section. Fig. 2 is a transverse vertical section taken on the line :0 x of Fig. 1, some parts being broken away and some parts being removed. Fig. 3 is a vertical section taken on the line 90" x of Fig. 1. Fig. 4 is a section taken through a portion of the device on a line at right angles to the line 00* :0 of Fig. 1, the parts being shown on an enlarged scale. Fig. 5 is a view corresponding to Fig. 1, but illustrating a modified construction, some parts being broken away. Fig. 6 is a vertical section taken on the line a; as of Fig. 5, and Fig. 7 is a vertical section taken on the line 90 :0 of Fig. 5.

Referring first to the construction illustrated in Figs. 1 to 4, inclusive, 1 indicates the vertical legs, and 2 the cup-equipped belt, of a grain-elevator, which belt runs over an upper pulley or wheel (not shown) and over a roller pulley or wheel 3. The shaft of the pulley 3 is journaled in suitable bearings 4, that are supported by metal beams 5, which are spaced apart on opposite sides of said pulley 3 and are rigidly secured at their ends to the pan 6 of the elevator. This part 6 constitutes a common bottom to the elevator boot and the pit, all as will hereinafter more fully appear. The grain-pits 7 are located one on each side of the pan 6, and the inclined bottoms of these pits 7 are contracted from their outer toward their inner extremities and deliver into said pan through dooropenings 8, formed in the central lower portions of transverse vertically-disposed partition-plates 9. These door-openings 8 are adapted to be opened and closed at will and to any desired eXtent by vertically-movable doors or valves 10. Verticallydisposed guide-rods 11 are rigidly secured at their lower ends to the doors 10 and are mounted to slide vertically through guide-sleeves 12, that are rigidly secured to projecting arms 13 on the respective partition-plates 9. The pan 6 flares in a direction transverse of the plane of rotation of the pulley 3, as best shown in Fig. 2, so that large openings are left at 14 between the beams 5 and the upper side edges of the said pan 6. Sheet-metal plates 15 connect the outer edges of the partition-plates 9 and at their lower edges are riveted or otherwise secured to the sides of the pan 6, thereby forming intermediate pits 16 between the grainpits 7 and on opposite sides of the conveyor-belt 2.

By reference to Figs. 2 and 3 it will be seen that the elevator-legs 1 terminate a considerable distance above the beams 5 and prefer ably above the upper portion of the pulley 3, the said legs being anchored to the partition-plates 9 by angle-bars 17 or similar devices. Secured to the beams 5 and depending one on each side of the pulley 3 is a pair of guard-plates 18, the lower edges of which follow a proximately the lower portion of said pulley 3 and prevent the grain from piling up against the sides of said pulle In the construction illustrated in Figs. 1 t0 4, inclusive, the pan 6 is polygonal in longitudinal section, and the guard-plates 18 are of corresponding form. In the construction illustrated in Figs. 5, 6, and 7 the pan 6 is bent on the line of a curve corresponding closely to the line of travel of the outer portions of the buckets on the belt 2, and the guard-plates 18 are correspondingly formed. In both constructions the guard-plates 18 terminate far above the bottom of the said pan 6, sothat when grain accumulates in the bottom of the pan it may flow upward through the passages marked 19 and may enter the spaces marked 20, which spaces may there is an excessive supply of grain.

be appropriatley designated as accumulation-chambers." The grain will be delivered into the pits 7 and will be fed into the pan 6 through the openings 8, where it will be taken up by the cups of the belt 2. When the grain is delivered into the pits faster than it can be takenup by the elevator-belt, it will flow to. a considerable extent through the openings'19, will rise within the accumulati g chambers or spaces 20, and when there is a shortage in the supply this accumulated rainwill run back into the pan 6, and thus keep up an even supply of grain to the elevator-belt. Furthermore, these accumulationchambers prevent an excessive pressure of the grain against the elevator belt when The guard-plates 18, as already pointed out, hold the grain out of direct contact with the sides of the pulley or wheel 3. They also constitute the inner sides of the accumulationchambers 20.

' With the device described there is very little possibility of clogging of the grain; but

should a clogging occur easy access is had to the clogged parts, as a person may readily enter the intermediate pits 16 and from the bottom thereof may reach any and all parts of! the pulley and elevator-belt.

By using a common pan to correspond to what is generally designated as the boot and pit simplicity and cheapness of construction are attained, and, furthermore, the action of the device is improved.

I claim as my invention 1. In a device of the kind described, the combination with a cupequipped elevatorbelt and cooperating leg, of a pan forming a bottom to said leg, said pan having an open accumulation chamber or space at one side, of a pit having an inclined bottom directly secured to one end of said pan and arranged togdeliver grain directly into said pan, subst ntially as described.

2. In a device of the kind described, the combination with an elevator-leg, of a pan secured to and forming a bottom to said leg, a wheel at the lower end of said leg, working in said pan, a cup-equipped elevator-belt working in said leg and running under said Wheel, an open accumulation-chamber in one side of said pan, an open pit leading upward from said accumulation-chamber, and an end pit having an inclined bottom directly secured to one end of said pan and arranged to deliver grain directly into said pan, substantially as described.

3. In a device of the kind described, the combination with an elevator-leg, and a pan secured to the lower portion of said leg and having a bottom thereto, a wheel journaled at the lower portion of said leg and working in said pan, a cup-equipped elevator-belt running under said wheel and through said leg, accumulation-chambers at the sides of said pan, intermediate open pits leading upward from said accumulation-chambers, and positively disposed end pits having inclined bottoms directly secured to the ends of said pan and arranged to deliver grain directly into said pan, substantially as described.

4. The combination with elevator-legs 1, a pulley 3, and a cup-equipped elevator-belt 2, of a pan or boot 6 below said pulley 3, guardplates 18 embracing the lower side portions of said pulley and forming said pan with accumulation-chambers 20, grain-pits 7 opening into the front and rear ends of said pan 6, and intermediate pits 16 opening into said accumulation-chambers 20, substantially as described.

5. The combination with elevator-legs 1, a pulley 3, a cup-equipped elevator-belt 2, of a pan 6 below said pulley, the beams 5 secured with respect to said pan and supporting bearings for the shaft of said pulley, the inclined end pits 7 opening into the front and rear ends of said pan 6 through openings-8, the

guard-plates 18 secured to said beams 5 and embracing the lower side portions of said pulley and forming said pan 6 with upwardlyextended accumulation chambers 20, and the intermediate side pits 16 opening into said accumulation-chambers 20, said pan 6 affording a boot to the elevator, and a common bottom to the said pits 7 and 16, sub stantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

FRED .W. COOLEY.
